The proliferation of pits and ponds created in recent years by miners dredging for small deposits of alluvial gold in Peru's Amazon has dramatically altered the landscape and increased the risk of mercury exposure for indigenous communities and wildlife, a new study shows. The study, published in Science Advances Nov. 27, found a 670% increase in the extent of ponds across the landscape in heavily mined watersheds since 1985. These formerly forested landscapes are now increasingly dotted by these small lakes, which provide low-oxygen conditions in which submerged mercury—a toxic leftover from the mining process—can be converted by microbial activity into an even more toxic form of the element, called methylmercury, at net rates 5-to-7 times greater than in rivers. The miners use mercury, a potent neurotoxin, to separate ore from soil and sediments, often without adequate safety precautions to protect themselves or the environment. Some of the mercury used by the miners is burned off into the air or spilled into nearby rivers, creating far-reaching environmental and human health risks. Artisanal and small-scale gold mining (ASGM) is now believed to be the largest global source of anthropogenic mercury emissions.

Four gunmen shot and killed local anti-mining activist Fikile Ntshangase at her home in South Africa's KwaZulu-Natal province Oct. 22. Ntshangase, 65, was a leading member of the Mfolozi Community Environmental Justice Organisation (MCEJO), which is taking legal action to prevent the expansion of an open-cast coal mine at Somkhele, on the southeastern border of the Hluhluwe-iMfolozi game park. MCEJO also says the mine's existing operations should be halted because they are not compliant with environmental and other laws.

Luis Arce, candidate of the party of ousted president Evo Morales, has seemingly swept to victory in Bolivia's Oct. 18 presidential elections. While the official count is technically still pending, results place him with more than 50% of the vote—well above the second-place center-right contender Carlos Mesa and with far more than the required majority to avoid a runoff. This represents a significant recoup of losses for the Movement Toward Socialism-Political Instrument for the Peoples' Sovereignty (MAS-IPSP), which Morales nominally still leads from exile in Argentina. As news of the victory broke, supporters gathered outside Arce's campaign office to chant "The pollera will be respected!"—a reference to the traditional skirt that has become a symbol of the MAS-IPSP indigenous base. But Arce is insisting there will be "no role" in his government for Morales, who has been barred by the courts from holding public office and faces criminal charges in Bolivia.

Six Portuguese young people have filed a legal complaint at the European Court of Human Rights  (ECHR) in Strasbourg, France, accusing 33 countries of violating their right to a secure future by failing to take action to mitigate the climate crisis. The youths aged 12 through 21, represented by the Global Legal Action Network (GLAN), are targetting countries whose policies on carbon emission reduction they say are too weak to meet the 1.5 degrees Celsius goal of the Paris Agreement, citing the country ratings of the Climate Action Tracker. Named in the suit are the 27 European Union member states, as well as the United Kingdom, Switzerland, Norway, Russia, Turkey and Ukraine.

In a decision made very timely amid new mobilizations against oil and mineral operations on peasant and indigenous lands, Peru's high court last month struck down a provision of the country's penal code that rights advocates said criminalized the right to "social protest." The July 6 ruling by the Constitutional Tribunal voided an amendment to Article 200 of the Penal Code that had been instated under Legislative Decree 1237, issued by then-president Ollanta Humala in September 2015. The decree expanded the definition of "extortion" to apply not only to use of force to gain "economic advantage" but also "advantage of any other nature." This expanded definition has been used to bring criminal charges against protesters who have blocked roads or occupied oil-fields or mining installations. The legal challenge to the decree was brought by an alliance of regional human rights organizations led by the Legal Defense Institute (IDL). (IDL, Servindi, July 7)

Russian President Vladimir Putin declared a state of emergency June 3 after 20,000 tons of diesel oil leaked into a river within the Arctic Circle. The spill went unreported for two days, which may have caused irreparable damage to the region. The spill was caused by the rupture of a fuel tank at a power plant on the Ambarnaya River near the Siberian city of Norilsk, Krasnoyarsk Krai. The plant is owned by Norilsk-Taymyr Energy Company, a subsidiary of Norilsk Nickel (Nornickel), which is the world's leading nickel and palladium producer. The company had reportedly spent two days trying to contain the spill, before alerting the government. The Russian Investigative Committee (SK) has launched a criminal case over the pollution and alleged negligence. The director of the power plant, Vyacheslav Starostin, has been taken into custody but has not yet been charged.

Indigenous leaders are warning that a combination of neglect, inadequate preparations, and a lack of lockdown measures is exposing remote and vulnerable communities in the Amazon to potentially devastating outbreaks of COVID-19. The nationwide death toll in Brazil has soared above 11,000 amid growing anger at President Jair Bolsonaro's dismissive response. The situation is particularly bad in the Amazon gateway city of Manaus, where the number of fatalities is feared to be many times the official 500 to 600. Peru and Ecuador also have large outbreaks and significant Amazonian indigenous populations.

Peru's right-wing opposition leader Keiko Fujimori, who had been jailed in January while corruption charges are pending against her, was released from pre-trial detention at Lima's Chorrillos prison on May 4, ostensibly on fears she could be exposed to the coronavirus. Fujimori will be under "restricted release," meaning she cannot leave Lima without prior authorization and must check in every 30 days with judicial authorities. Of course there has been no general discharge from Peru's dangerously overcrowded prisons, and one leading anti-corruption prosecutor in the Fujimori case, Rafael Vela, is protesting her release as "illegitimate." (Milenio, Japan Times, Diario Uno)
